项目用node+express+ejs写的h5页面，所有的数据都是通过调取java第三方接口的数据，然后用ejs渲染，放到测试环境测试的时候不间断的服务挂掉、报错"502 Bad Gat eway"nginx错误，请问如何解决呢？是获取接口的数据的问题吗？
例如获取接口的代码:
router.get(’/:id’,function(req,res,next){
const params = {
id:req.params.id
}
request({
url: ${API}course/detail,
method: req.method,
json: true,
headers: {
“content-type”: “application/json”,
},
qs: params
}, function(error, response, body) {
if (!error && response.statusCode == 200) {
res.render(‘learn’,body)
}
});
})
@rrbe 加了pm2，自动重启了，错误代码是这样 at new StatusCodeError (/apps/srv/instance/nodejs/node_modules/request-promise-core/lib/errors.js:32:15) at Request.plumbing.callback (/apps/srv/instance/nodejs/node_modules/request-promise-core/lib/plumbing.js:104:33) at Request.RP$callback [as _callback] (/apps/srv/instance/nodejs/node_modules/request-promise-core/lib/plumbing.js:46:31) at Request.self.callback (/apps/srv/instance/nodejs/node_modules/request/request.js:186:22) at emitTwo (events.js:106:13) at Request.emit (events.js:191:7) at Request.

@coordcn 加个pm2后，发邮件报了个这样的错误 at new StatusCodeError (/apps/srv/instance/nodejs/node_modules/request-promise-core/lib/errors.js:32:15) at Request.plumbing.callback (/apps/srv/instance/nodejs/node_modules/request-promise-core/lib/plumbing.js:104:33) at Request.RP$callback [as _callback] (/apps/srv/instance/nodejs/node_modules/request-promise-core/lib/plumbing.js:46:31) at Request.self.callback (/apps/srv/instance/nodejs/node_modules/request/request.js:186:22) at emitTwo (events.js:106:13) at Request.emit (events.js:191:7) at Request.
